thegunner100 did a good job of digging up the quotes from Jason. I still have the "O" rings on my tubes. When I initially documented the process, the tubes seemed to really quiet down from a microphonics standpoint when the RTV silicon was starting to cure. Once it finished curing, there was very little improvement in the noted microphonics issue. Basically, it's a "feature" with the Vali amp and nearly impossible to work around. But, Schiit has apparently been selecting the tubes to minimize the effects to a degree.
Now, putting all the jibber-jabber aside, we all just need to appreciate what it really is. A $119 amp that's capable of "showing up" the competition a few hundred bucks north of $119. I've been swapping amps all around over the past few years. The Vali is the real deal. Enjoy the amp, put the rest of your cash aside for other upgrades or music.
To get the most out of the Vali:
1) Turn the amp on.
2) Plug in your headphones - preferably with a headphone extension to keep from moving the amp.
3) After about 30 seconds, place the headphones on your head.
4) If you need to apply volume adjustments, do it with the level adjustment in your player itself (e.g. Foobar).
* Keep the amp on a solid surface so it doesn't jiggle or shake around.
* Talk nice to it.
* Appreciate what you have and the bargain you've obtained for $119.00.
* Enjoy your music!
